Which testing instruments are needed for cable fault detection? Cable laying is the sub-construction with the greatest economic value in electromechanical installation and construction, and it is also an important facility to ensure the normal operation of the equipment. In the actual construction and maintenance operation, the cable fault detection is often not designed due to the laying method. Which testing instrument cables need to be laid is the sub-construction with the greatest economic value in the electromechanical installation and construction, and it is also an important facility to ensure the normal operation of the equipment. During the actual construction and maintenance operation, it is often due to the unreasonable design of the laying method and the improper operation of the construction personnel. The influence of various factors such as the destruction of small animals such as insects and rats will cause damage to the cable and cause failure. In a large number of engineering practices, we found that the cable fault is a high-resistance current leakage fault (resistance value greater than or equal to 1Ω), which is often caused by damage to the insulating layer. Low-resistance faults are generally short-circuits between phases or to ground. They often occur at the branch head of the cable. They are caused by insufficient insulation during construction, but the probability of occurrence is very small. The main reason is prevention. Reduce the occurrence of accidents.
